从KnpPaginatorBundle获取错误的标签

Question

今天第一次在symfony 3项目上安装了KnpPaginatorBundle，并得到了奇怪的bug。而不是前一个和下一个按钮，我得到了“label_previous”.和"label_next“。我以前做过一些实验，将语言添加到config.yml中，但是在今天恢复它们之后，我仍然没有得到正确的按钮标签。

还有我的config.yml

Answer 1

此模板文件twitter_bootstrap_v3_pagination.html.twig使用trans小枝筛选器获取标签的名称。例如，您可以在以下部分看到这一点：

<span>&laquo;&nbsp;{{ 'label_previous'|trans({}, 'KnpPaginatorBundle') }}</span>

trans过滤器(reference.html#trans)试图在特定的上下文中定位翻译的配置文件。您的上下文是KnpPaginatorBundle，因此它将在这个包中搜索一个翻译文件。看看这里：https://github.com/KnpLabs/KnpPaginatorBundle/tree/master/Resources/translations。

每个区域设置都有一个翻译文件，但如果应用程序默认区域设置不在此列表中，则不会进行翻译。

但是，如果您的区域设置为en，并且仍然无法工作，您可以自己制作模板并手动放置标签。

在三个简单的步骤中这样做。

1：在app/Resources/views文件夹下创建一个名为pagination.twig.html (或类似的文件)的新文件。

2：复制文件twitter_bootstrap_v3_pagination.html.twig的代码并粘贴到新创建的文件中。然后，更改引用trans过滤器的行。示例：

线：<span>&laquo;&nbsp;{{ 'label_previous'|trans({}, 'KnpPaginatorBundle') }}</span>

您应该编辑到：<span>&laquo;&nbsp; Previous</span>

3：在app/config/config.yml中更改knp_paginator/app/config/config.yml/分页键中的文件。应该是这样的：

#KNP
knp_paginator:
    page_range: 5                      # default page range used in pagination control
    default_options:
        page_name: page                # page query parameter name
        sort_field_name: sort          # sort field query parameter name
        sort_direction_name: direction # sort direction query parameter name
        distinct: true                 # ensure distinct results, useful when ORM queries are using GROUP BY statements
    template:
        pagination: 'pagination.html.twig'
        sortable: 'KnpPaginatorBundle:Pagination:sortable_link.html.twig' # sort link template
